Trailing the march was another, quiet procession of servants. They carried Lilac’s body, wrapped in their coats. The girl whose death had precipitated a war was all but forgotten.

As Sano trudged along, he felt ill with horror about the massacre. Detective Marume said, “I’ve met samurai bullies in my time, but these boys are the worst.”

“They’re like a wolf pack,” Fukida said.

The Rat moaned, “Merciful Buddha, transport me back to Edo!”

Hirata’s face was set in tight lines of anguish and fury as he watched the chieftain prodded and tormented along. Through Sano’s horror rang guilt. If he’d solved the murder sooner, he might have prevented the massacre. Now he must do something to forestall more senseless slaughter.

At Fukuyama Castle, sentries at the gate greeted the troops like returning heroes. They mounted the severed heads on pikes outside the castle wall. The army cheered Lord Matsumae: “Hail to the future conqueror of Ezogashima!”

He smiled but looked perplexed, as if he didn’t quite understand what had happened. Sano rushed over to him. “Lord Matsumae, please call off the war. Even if Chieftain Awetok or Urahenka did kill Tekare, their people had nothing to do with it.”

They’re guilty by association,“ Lord Matsumae said.

“Japanese law says that a criminal’s kin must share his punishment,” Gizaemon added.

“Only his immediate family and close associates,” Sano said. “It would be unfair to kill the other tribes.”

“These bastards are all related as far as we’re concerned,” Gizaemon said.

If reason wouldn’t get through to them, maybe threats would. “The shogun won’t want a war. You’re already in trouble with him for disrupting trade with the natives. A war will stop it altogether. He’ll throw your clan out of Ezogashima and turn you all into masterless samurai.”

Another cheer regaled Lord Matsumae. He raised his arms, beaming. Gizaemon said, “Trade will be better than ever after we wipe out the barbarians. We’ll open up Ezogashima to every Japanese who wants to hunt game or mine for gold. There will be more wealth for the shogun.”

“Ezogashima’s a huge place. Your troops will be spread thin. You’ll need reinforcements from the Tokugawa regime, from other samurai clans. That won’t make Lord Matsudaira happy. He needs everybody to help him fight the rebels who are trying to depose him.”

“We’ll win a fast victory.” Gizaemon sounded confident. “Lord Matsudaira will thank us for bringing him more riches to pay his army and his allies.”

The castle gate opened. Troops swarmed through, carrying Sano in on the tide of their uproar. He fought to stay near Lord Matsumae and Gizaemon. “The practical details are against you. There’s a plague among your men. And winter is no time to launch a military expedition. If there’s this much snow here, how deep is it in the far north?”

“We won’t go there yet,” Lord Matsumae said. “We’ll attack the nearest villages and save the others for spring.” He cried, “Let’s drink to our future victory!”

“At least wait until I finish investigating the murder,” Sano pleaded.

“You are finished.” Sudden anger enflamed Lord Matsumae. “I put my faith in you, and you’ve let me down. I’m taking back charge of the investigation. I’ll find out who killed Tekare by persuading our prisoners to tell the truth.”

“Best idea I’ve heard in a long time,” Gizaemon said. “I’ll help. Let’s go.

Horror struck Sano because he knew what they intended. Hirata said “No!” and rushed forward to save Urahenka and Awetok from the troops herding them like animals.

Captain Okimoto said, “I wouldn’t do that if I were you, Hirata-san.” Rowdy, grinning soldiers aimed bows at Sano. One loose finger could end his life. Hirata stared in frustration and rage.

“Let Hirata-san and me come with you,” Sano said to Gizaemon. Maybe he could keep things from getting out of hand. Maybe he was a deluded fool.

“All right,” Lord Matsumae said. “I’ll show you how an interrogation is done.”

At the women’s quarters, the troops locked the native concubines in their rooms. Reiko found herself thrown together with the Japanese ladies in theirs. Maids stoked braziers and brewed tea. The ladies-in-waiting fussed over Lady Matsumae. They removed her coat, wrapped her in quilts, and rubbed her cold hands and feet. No one paid any attention to Reiko. She knelt in a corner, spent by the day’s events.

Discovering Lilac dead and learning that she’d been murdered had been bad enough. Reiko was aghast that it had led to a war. How many of the natives had been slaughtered? Reiko feared for Sano. Would he be killed in the fight? Would she lose her husband as well as her son?

Guilt filled Reiko. She’d been so immersed in her own loss that she’d done nothing to help Sano. If they never saw each other again, this separateness would be her last memory of him. Reiko felt such a debilitating exhaustion and despair that she wanted to lie down and sleep through whatever happened.

Lady Matsumae retched into a basin and vomited while the ladies-in-waiting held her head. “The sight of that girl was just awful,” she groaned. “So was the fight. All that blood! I can’t get it out of my mind.”

Lady Smart offered her a cup of herbal tea. “Drink this. It’ll settle your stomach.”

“I can’t.” Lady Matsumae gagged and shivered. “I feel so cold. I feel dirty from being around death all day. It’s rubbed off on me.”

“A hot medicinal bath will help you,” Lady Pansy said.

Reiko experienced a renewal of the anger that had sent her looking for Lilac. Now that the girl was beyond reach and Reiko could forgive her, the anger found a different focus. Such terrible things had happened, and all Lady Matsumae did was make work for other people. Reiko’s earlier resentment toward Lady Matsumae deepened into hatred. She had no sympathy left for this woman who’d lost her daughter. Reiko had lost her son, and her own daughter, Akiko, was too far away to be any comfort. Lady Matsumae didn’t deserve special consideration or the right to behave selfishly. Lilac had at least given Reiko warm clothes. Lady Matsumae had offered nothing whatsoever. And Reiko wondered if Lady Matsumae was at fault for more than that.

Her attendants helped Lady Matsumae out of the room. Reiko followed them down the corridor, stood outside the door of the bath chamber, and listened. Water splashed while the attendants washed Lady Matsumae. When they left her alone to soak in the tub, Reiko sneaked into the chamber.

It was a small room with a raised floor of wooden slats. Mats on the walls had a pattern of leafy green plants woven into them, for visual warmth. In the center was a round, sunken tub. Lady Matsumae sat submerged up to her chin. Her head lolled; her eyes were closed. The water steamed up in clouds that smelled of sweet, pungent herbs. Reiko had a sudden image of Lilac dead in the hot spring. For an instant she felt Lilac’s inert flesh, saw the boiled-fish eyes staring sightlessly at her. The sensations nauseated her and fueled her anger.

“Wake up, Lady Matsumae,” she ordered.

“Uh?” Lady Matsumae’s head jerked up. Her eyes snapped open.

She looked older without her makeup, her complexion sallow, mottled, and loose, her mouth pale and puffy. Hostility focused her bleary eyes. “What do you want?”

“To talk.”

“Well, I don’t want to,” Lady Matsumae said peevishly. “Go away.” She lay back, shut her eyes, and compressed her lips.

“I’m not leaving.” Reiko had ideas about what had happened to Lilac, and she had bones to pick with Lady Matsumae. She dipped her hand in the tub and splashed water in Lady Matsumae’s face.
